如何将彩色文本输出到Linux终端?

如何将彩色字符打印到支持彩色字符的Linux终端?

如何判断终端是否支持颜色码?

这是一个老主题，但我编写了一个类，其中包含嵌套子类和由简单C宏定义的颜色静态成员。

我在dreamincode.net中通过用户no2pencil从这篇文章中获得了颜色函数。

我这样做是为了能够像这样使用std::cout流中的静态常量:

cout << zkr::cc::fore::red << "This is red text. " 
     << zkr::cc::console << "And changing to console default colors, fg, bg."
     << endl;

类和测试程序的源代码可以在这里下载。

cc::console将重置为控制台默认颜色和属性，cc::underline将为文本下划线，这在putty上工作，我已经测试了测试程序。

颜色:

black
blue
red
magenta
green
cyan
yellow
white

lightblack
lightblue
lightred
lightmagenta
lightgreen
lightcyan
lightyellow
lightwhite

它可以用于cc静态类的前静态和后静态子类。

为了更实用，我在这里添加了类代码。

颜色代码宏:

#define CC_CONSOLE_COLOR_DEFAULT "\033[0m"
#define CC_FORECOLOR(C) "\033[" #C "m"
#define CC_BACKCOLOR(C) "\033[" #C "m"
#define CC_ATTR(A) "\033[" #A "m"

main color函数定义屏幕的颜色或属性:

char *cc::color(int attr, int fg, int bg)
{
    static char command[13];

    /* Command is the control command to the terminal */
    sprintf(command, "%c[%d;%d;%dm", 0x1B, attr, fg + 30, bg + 40);
    return command;
}

其他回答

从我的理解，一个典型的ANSI颜色代码

"\033[{FORMAT_ATTRIBUTE};{FORGROUND_COLOR};{BACKGROUND_COLOR}m{TEXT}\033[{RESET_FORMATE_ATTRIBUTE}m"

由(名称和编解码器)组成

FORMAT ATTRIBUTE { "Default", "0" }, { "Bold", "1" }, { "Dim", "2" }, { "Italics", "3"}, { "Underlined", "4" }, { "Blink", "5" }, { "Reverse", "7" }, { "Hidden", "8" } FORGROUND COLOR { "Default", "39" }, { "Black", "30" }, { "Red", "31" }, { "Green", "32" }, { "Yellow", "33" }, { "Blue", "34" }, { "Magenta", "35" }, { "Cyan", "36" }, { "Light Gray", "37" }, { "Dark Gray", "90" }, { "Light Red", "91" }, { "Light Green", "92" }, { "Light Yellow", "93" }, { "Light Blue", "94" }, { "Light Magenta", "95" }, { "Light Cyan", "96" }, { "White", "97" } BACKGROUND COLOR { "Default", "49" }, { "Black", "40" }, { "Red", "41" }, { "Green", "42" }, { "Yellow", "43" }, { "Blue", "44" }, { "Megenta", "45" }, { "Cyan", "46" }, { "Light Gray", "47" }, { "Dark Gray", "100" }, { "Light Red", "101" }, { "Light Green", "102" }, { "Light Yellow", "103" }, { "Light Blue", "104" }, { "Light Magenta", "105" }, { "Light Cyan", "106" }, { "White", "107" } TEXT RESET FORMAT ATTRIBUTE { "All", "0" }, { "Bold", "21" }, { "Dim", "22" }, { "Underlined", "24" }, { "Blink", "25" }, { "Reverse", "27" }, { "Hidden", "28" }

有了这些信息，就很容易给字符串“I am a banana!”上色，前景色为“黄色”，背景色为“绿色”，就像这样

"\033[0;33;42mI am a Banana!\033[0m"

或者用c++库着色

auto const& colorized_text = color::rize( "I am a banana!", "Yellow", "Green" );
std::cout << colorized_text << std::endl;

试试我的标题这里一个快速和简单的方法来着色文本:Aedi的颜色标题

Escape-Sequence-Color-Header

在Unix中使用c++为输出着色!!

文本属性选项:

ATTRIBUTES_OFF, BOLD, UNDERSCORE, BLINK, REVERSE_VIDEO, CONCEALED

颜色选择:

BLACK, RED, GREEN, YELLOW, BLUE, MAGENTA, CYAN, WHITE

格式:

通用格式，在$变量$中包含你想要的值

COLOR_$Foreground_Color$_$Background_Color$
COLOR_$Text_Attribute$_$Foreground_Color$_$Background_Color$
COLOR_NORMAL  // To set color to default

e.g.

COLOR_BLUE_BLACK // Leave Text Attribute Blank if no Text Attribute appied
COLOR_UNDERSCORE_YELLOW_RED
COLOR_NORMAL

用法:

只是使用流的颜色，你想在输出文本和在输出文本后再次使用以将颜色设置为正常。

cout << COLOR_BLUE_BLACK << "TEXT" << COLOR_NORMAL << endl;
cout << COLOR_BOLD_YELLOW_CYAN << "TEXT" << COLOR_NORMAL << endl;

在OSX shell上，这为我工作(包括“红色文本”前面的2个空格):

$ printf "\e[033;31m  red text\n"
$ echo "$(tput setaf 1)  red text"
